This post is about Oz Kara slug for 12 gauge shotguns.
OZ-KARA 12 Gauge slug is a Brenneke-style solid lead slug with copper ball inside. This ball fragments slug into several parts when it hits the target. Also it allows better penetration of the target.
OZ-KARA slug has fins cast onto the outside and a plastic wad attached to the projectile. This wad serves as a gas seal and stabilizez slug after firing.
I have not tested it but heard good feedback about Oz Kara slug. This can be a good choice for reloading.
I plan to get a Lee Load-All 12 reloader soon and test different types of slugs for a shotgun.
